SPECIFICATION forming part of Letters Patent No. 423,176, dated March11, 1890.

` Application tiled August 27. 1883. Serial No. 283,936. (No model.)

To @ZZ whom, it may concern.-

Be it known that we, ALBERT NEY, a citizen of the United States,residing at Dubuque, in the county of Dubuque and State of Iowa, andJOSEPH BAUMGARTNER, a subject of the King of Bavaria, also residing atDubuque,

in the county of Dubuque and State of Iowa,

have jointly invented certain new and useful Improvements in FoldingDoors, of which the following is a speciiication.

Our invention relates to that class of folding doors which are supportedupon hangers attached to the inner edge of the door and to thedoor-frame, which will permit the door to be moved across the doorwaywithout contact with either the floor or the cap of the frame.

The object of our invention is to dispense with guideway -"rails,rollers, and slots, and to support and balance the door, that it may beeasily adjusted to the required position and to a plane of movement freeof both the floor and the cap-frame, and the supports of which will befree from frictional or sliding contact with the inner edge of the doorand with theqframe upon which it is supported.

To this end our improvements consist in certain novel combinations andpeculiar arrangement of parts, which will hereinafter be fully describedin uthe annexed specit`1` cation, and particularly pointed out in theclaims, reference being had to the accompanying drawings, in which-Figure 1 represents a side elevation of the door and a part of itsframe, the partitioncovering being omitted to more clearly illustratethe operating mechanism. Fig. 2 is a side view of a portion of4 thedoor-frame, showing the mechanismj-,which operates the door in theposition it assumes when the door is partly closed. Fig. 3 is a similarView showing the parts in the position they assume when the door isfully closed. Fig. 4 is a detail view in elevation of a modified form ofone of the segment-plates and the conn ectingarmforming partof themechanism for opery ating the door.` `Fignis van venlarged detail viewof a modified arrangement of some of the operating mechanism'.

Fig. 8 is a detail side View of oneof the segments provided with a Xed arm or extension. Fig. S" is asection taken on the line Z7 b, Fig. 8. Fig. 8C is asection on the line.r it, Fig. 8. Fig. 9 is a detail side view of one of the segmentsprovided with an adjustable arm or extension. Fig. 9b is a verticalsection on line b b, Fig. 9. Fig. 9c is a section of the adjustableconnection on line c c, Fig. 9; and Fig. l0 represents enlarged detailsof the upper corner of the door and edge strip detached.

In the accompanying drawings, A indicates the door, which is hung in theframe BJ, which consists of a sill B', a cap-piece B2, posts B3, andstudding B4. -Said posts and studding B3 .4 are in practicalconstruction covered over to form a pocket G, into which the door ismoved when opened. The door is supported upon a hanger consisting of adouble system of bars E, arms F G, and links H, coupled together andpivotally connected to a bracket I, secured to the door-post B3,the-outer ends of the bars E being pvotally connected to the top andbottom of the inner edge of the door.

The arms F are provided with toothed segments F', geared together, andare pivoted at f to the vertical arm I3 of the bracket I.

Fig. 7 is a per- The outer end of said arms are pivoted at f i thusfollow the horizontal frame-pieces of the door as the said bars areswung in either direction away from a vertical position.

The bars E are braced and sustained to support the door in an uprightposition by arms G, provided with toothed segments G, geared together,and by the links ll, which are pivoted to and connect the outer ends ofsaid arms G. to the bars E at. a suitable distance from the pivot f atthe ends of the said bars to form hinged pivoted parallelograms at theinner ends of the bars E, which are geared which means the door may beeasily removed together and support the door in anyn position in whichlit may-be placed.orreciprocated.`

The arms G and link H being coupled together by the segments G', asdescribed, are thereby adapted to be simultaneously moved toward or fromeach other to react oneupon. the other, and thus cause the outer endsof' sections G, we connect the said gear-segments to the arms G in themanner most clearly shown in Fig. 4 of the drawings, from which it willbe seen that the segment G- is provided with an elongated-slot, inwhichiits a sliding pivot-block, the lower end of which is pro? videdwith an aperture torecei-ve a securing-` screw, while its upper end isprovided with an opening to receive the pivot-pin f. The outer 4ends ofthe hanger-bars Eare connected bythe edge strip 7c,said bars beingpivoted uponithe pins c e', secured,respectively, to the upper and loweredges of said strip, whichis fitted uponl the inner edge of the door bymeans of studs or hooks 7a and the slotted vplates a, which areinterlocked with each other'vbyvsliglitly lowering` the door after thehooks-havefbeen fitted into said plates, and which may be-re-v leasedtherefrom by slightly-lifting the door' and withdrawing the hooksfromthe,slots,2by

from the hanger.

l The edge strip 7c is held `parallel tothe'inner edge of the doorwithout being in closeA contact therewith by the slotted plates a, atk

the upper and lower ends thereof, above described,- and by a rubberblock vor cushion a2, held upon the inner edge of the door ybetween itand the strip k, and a similar cushion as upon the outer face of saidstrip, whiclren` gages a fixed part of the door-frame,-said cushionsserving to deaden the jar yof fthe' door against the back part of thepocket when the door is thrown violently Y-back into' the said pocket.

-By reference to Fig. -10 itV will be observed that the stud-pin e issecured to a-block e?,- adjusted in a cross-slot e3 in a plate e4 uponthe upper end of the edge strip cby means' of screw e5, passing throughsaid plate and block, by means of which the pivotal point of support atthe upper end of the door is shifted to bring the outer vertical edgeofthe door even with the door-frame, or, if dou-blel doors are used, toybring their meetingedges' together to form a close joint.

which in turn is pivoted to the swinging arms Said arms I I2 may beraised or lowered by means of a rocking arm I, pivoted to thelowerretaining-plate b', tovbear beneath the llower-arm I2. ofthebracket, andberadjusted to raise and lower the bracket, together with-the supporting-pivots, by means of a screw I7,

connecting said rocking arm and the plate b -fupon-the--post B3( InFigs. 5 to 9, inclusive,I have illustrated modified constructions of thebracket I and the vmeans for adjusting the pivot-connections of the armsF and G. By referring to Sheet 3 of the drawings it will be observedthat ,Ilaform the upper arm I" of the bracket ,with an adjustable pivoti, which is secured to a sliding boX'D`, Working in an elongated slot din the upper plate D, secured to the post B3, as shown, andwhich isVadjusted by means of the-screw CZ', passingl through the block-D3andsideflanges d?. v By thismeans theplate I3,which carries the pivot f,is moved at its 'upper endtovary the position ofsaid supporting-pivotand thereby cause the door --to move'in the required horizontalplane.When v'thusy adjusted, the set-screw dis 1securedby a lock-nut' cl3,fitting upon Athe 'vend thereof to bear against the inner flange oftheplate D. I also provide the lower end of the vertical plate I'ofthebracket'I with a vnotch 5,- in which fits a cross-pin i* on the=lowerend ofa diagonally-disposed trace-harp, the upyper end ofwhich-connectswith'an adjustingv screw I5, the upper end of which passes through thefront wall of the plate D, as-most clearlyfshown in Fig. 7 of thedrawings. The

hanger Iandy its brackets are-sw-ung out-into the doorway for removal,repairs, Yor .adjustment \by disconnecting theplate I3-fromthe arm I or'by unscrewing it sufficiently -to allowthe lower pivot 4 to drop fromtheslotv ted -end ofthe-arm I2 and plate I3.

Thearms I I2 may then be removed from-the postBB by removing thepivot-screws it" from the plates AD 'D'. --By thisconstructionwe'are en-*abledto obtain the same adjustment obtained ybythe rockin g-leverconstruction I6 I7; (Shown in'Fig. ll.)

In Figs. 8, S13-and 8C I illustrate the conwstructionof lthe arm F and-its gear-segment F and in Figs. 9, 9b, and 9CI show-the-p'eculiarconstruction of one of the Varms G, its 'gearsegment-G', and theintermediate adjusting V-devices whereby the pivotal point of the doormaybe shifted, said devices being provided -by-forming the arInG withaslot-g', in which fits a pivot-block g, torwhich is connected the upperend of -a bar g2, to thelower end vof which is connected one end of anadjustingscrew g3,the lower end of which vengages a `wing g5, formed onthe gear-segmentG.- The The bracket I,(shown in Figs. 1,2, and 3,) fconsists of a vertical plate I3, to which-the' varms'F and Gare pivoted,as before described,

'length of the throw of the arm G is ythus varied rand the extent ofthe-movement of the outer end -of the arms E thus correspond- IOO finglylengthened or shortened. From the be drawn together untilthe bars Eassume a vertical position, (shown in Fig. 2,) at which point the doorwill be half-Way closed, and the arms F and G will then be spread apartat their outer ends to carryT the door through the remaining portion ofits movement. The arms G and links H Will in the meantime have supportedthe bars E and door .in their upright position relative to each other bymeans of the segment-gear G', which has a diierential movement With thesegment-gear F in both directions.

A perfect parallel movement of the outer ends of the bars Eis thuseffected, if the connecting arms and levers be of proper lengths to formequal parallellograms connected with the inner ends of thesupporting-bars IVe desire it understood that We do not limit ourselvesto the precise constructions set forth to accomplish the results"stated, as these may be varied in a number of ways Without departingfrom the broad principle of our invention.

Having thus described our invention, what we claim, and desire to secureby Letters Patl.
